> Many people pay off their student loans last, as they're usually very low interest. You could have a student debt into your 40s but not because you can't pay it off - rather because it's cheaper than your mortgage. As explained below, no, the debt load that doctors hold is not very low interest. It's in the line of 8-10%. For contrast, I have credit cards that have APRs within striking distance of those rates, and that's consumer debt. You seem to be thinking of undergraduate student loan debt, which is heavily subsidized.
